Abstract
Abruption is a serious complication of pregnancy and a leading cause of maternal and perinatal mortality & morbidity. The objective of the study was to identify risk factors for placental abruption that may be amenable to interventions which can results in impaired feto maternal outcome.
Materials and Methods: This was a case control study conducted in SAT Hospital, Thiruvananthapuram. A total of 77 cases of abruption and controls were investigated. Statistical analysis for comparing low risk factors were done using Chi square test, Student's test and 'p' value, Odd's Ratio (OR) and confidence intervals were also calculated.
Results: There were 77 cases of abruption during the study period. Advanced maternal age (OR - 5.87, CI - 0.135-0.618), multiparty (OR - 4.6 CI - 1.2-18.1) were significantly associated with abruption. Increased incidence of abruption was found among low socioeconomic status and referred cases. PIH was a major risk factor associated with abruption (27.3% vs 9% in controls). P < 0.01
Conclusions: The results indicate that placental abruption is an obstetric emergency with maternal and perinatal mortality. Advanced maternal age, multiparity, low socioeconomic status were the major sociodemographic factors associated with abruption. Previous caesarian delivery and PIH were the obstetric risk factors for abruption.
Keywords: Risk factors, abruptio placentae, feto maternal outcome.
